Go Ask Alice is a controversial 1971 book about the life of a troubled teenage girl. The book continues its claim to be the actual diary of an anonymous teenage girl who became addicted to drugs, but this has been dismissed as false. Beatrice Sparks is listed as the author of the book by the United States Government. The novel is presented as a testimony against drug use. The diarist's name is never given in the book.

The story caused a sensation when published and remains in print as of 2011. Revelations about the book's origin have caused much doubt as to its authenticity and factual accounts, and the publishers have listed it as a work of fiction since at least the mid-late 1980s. Although it is still published under the byline "Anonymous", it is largely or wholly the work of its purported editor, Beatrice Sparks. Some of the days and dates referenced in the book put the timeline from 1968 until 1970.

The title is from the lyrics to the Jefferson Airplane song "White Rabbit". Grace Slick wrote the song based on perceived drug references in the classic novel Alice In Wonderland. (On July 14 [page 36 of the 2006 edition], the writer says she "feel[s] like Alice in Wonderland" and "maybe Lewis G. Caroll [sic] was on drugs too.")
